SAFETY- RAzo u.

SPECIFICATION forming part of Letters Patent No. 740,555, dated October6, 1903.

Application led April 20, 1903.

To if/ZZ whom it may concern:-

Be it knownthat I, JOHN GUINAN, a citizen of the United States, residingat Jamaica, in the county of Queens and State of New York,

have invented certain new and useful Im- ,n provements inSafety-Razors,of which the fol-y lowing is a specification.

The razor-blade and safety guard attachment involve novel features andare specially adapted to each' other, the purpose being simplicity,economy and lightness of structure, ease with which the guard may beremoved for cleaning, and the despatch and convenience with which it maybe placed in position. j

YFor a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following'description and drawings hereto attached. y

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a side view of a razor and safetyguard attachment embodying theessential features of the invention. Fig. 2 is a transverse section onthe line 2 2'of Fig. 1. Fig. 3 is a longitudinal section of thesafety-guard about on the -line X X of Fig. 1. Fig. 4 is a detailperspective view of the lock-lever. Fig. 5 is a detail perspective viewof the safety-guard. Fig. 6 is a detail perspective view of the pivotedclamp member.

Corresponding and like parts are referred to in the followingdescription and-indicated in all the views of the drawings by thc sainereference characters.

The razor-blade l and shank 2 may be of any design'. The shank, adjacentto the A blade, is provided with a rounded portion 3,

therefrom.

Serial No. 153,506. (No modell) Clip 8 is pivotally connected to theouter arm of guard 4, and clamp 9 is applied to the inner arm andreceives rounded portion 3 of shank 22 The upper end of arm 6 isoutwardly curved to form jaw 10, and said parts 6 and 10 constitute aclamp member rigid with guard 4. The movable or pivoted clamp member 1lis provided with jaw 12, curved in an opposite direction to jaw 10 andcoperating therewith to embrace and grip part 3. The connecting meansbetween the clamp members consist of tongue 13, pressed or struck frommember 11 and passed through opening 14, of arm 6 and bent against theouter side of said arm to hold clamp member.

11 in place, as shown most clearly in Fig. 2. Clamp member 11 isprovided upon its inner side with cam portion 15 for coperation withwedge 16, whereby the lower end of the' clamp members are pressed apartand jaws 1Q and in the way or interfere with convenient use of therazor. When the outer end of locki lever 17 is moved away from shank 2,wedge 16 is moved inward, thereby releasing the clamp and permittingsame to be turned from one side to the other of the blade or theattachment either to be fitted upon the blade or removed therefrom by anend wise sliding movement. When the parts are properly assembled and theguard is turned to lie against aside of the razor-blade, it is madesecure by pressing inward upon lock-lever 17, thereby moving wedge 16outward and spreading the outer ends of the clamp members, whereby jaws10 and l2 are caused to firmly and securely grip opposite sides of part3 of shank 2.

Clip 8 is of a shape to embrace the outer end portion of the razor-backand is slipped thereon by a longitudinal movement. When the guard liesagainst a side of the razorblade, the clamp or the part thereof belowshank 2 comes in the rear of the blade, thereby IUD c zer-back, and aclamp at the inner end of said preventing outward displacement of the lguard when pressing upon lock-lever 17 to secure the attachment.

Having thus described the invention, what is claimed as new isl. Incombination, a razor-blade, a safetyguard attachment, a clip havingpivotal connection with the outer end of the guard and adapted to befitted to the outer end of the razor-back, and a clamp at the inner endof said guard for gripping the shank of the razor-blade to hold saidguard in either one of its two positions, substantially as set forth.

2. In combination, a razor having a portion of its shank made rounding,a safety-guard attachment, a clip at the outer end of the guard to lbefitted to the outer end of the raguard and adapted to grip the roundedpo'rtion of the razor-shank to hold thev guard in proper position,substantially as specified.

3. A safety-guard attachment for razors provided with a clamp comprisingpivoi'allyconnected members, and a lock-lever'pivoted to one of saidmembers and provided with a Wedge portion to effect a spreading of theclamp members at one end and a closing of said members at the oppositeend to secure the guard in proper position, substantially as set forth.

4. In a safety-guard attachment for razors, a clamp com prisingpiVotally-connected members, a cam forming a side of the space betweensaid clamp members, anda lock-lever pivoted to a clamp member andadapted to cooperate with said cam to eect a spreading of the clampmembers at one end and a closing thereof at the opposite end to grip aportion of the razor and secure the guard in proper position,substantially as set forth.

5. In a safety-guard attachment for razors, a clamp comprising companionmembers, one of said members having an opening and the other memberhaving a tongue pressed therefrom to pass through the opening of thefirstmentioned member and bent to secure said members, and meanscoperating with the clamp members to cause them to grip the razor andhold thc guard in place, substantially as set forth.

6. In a safety-guard attachment for razors, a clamp comprisingpivotally-connected members, one of said members having a cam portionupon its inner side, and a lock-wedge pivoted to a member of the clampand adapted to coperate with the cam portion of the clamp to secure'theguard in proper position, substantially as setforth.

'7. The herein-described safety-guard attachment for razors, comprisinga guard having arms at opposite ends, one of said arms terminating in ajaw, a companion clamp member pivoted to the arm of the guard providedwith .the jaw, a lock-lever pivoted to the rigid clamp member andprovided with a Wedge to' operate between the clamp members to eect agripping action thereof, and a clip pivotedy to the outer arm of theguard, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
